To all whom it may concern Be it known that I, JOHN F. -WILLIAMS, acitizen of the United States of America, residing at Detroit, in thecounty of Wayne and State of Michigan, .have invented certain newanduseful Improvements in Sanding Devices for Automobiles, of which thefollowing is a specification, referencebeing had therein to theaccompanying drawings.

This invention relates to means for delivering sand to the surface of aroad bed adjacent to the traction Wheels 'of a motor vehicle to preventskidding,' and its object is to provide a device especially adapted foruse upon motor vehicles havingmeans for controlling the discharge ofsand which means may be automatically operated by the actuation of thevehicle brake, and having certain other new and useful features iii theconstruction and arrangement of parts, the invention consisting in thematters hereinafter more fully set 'forth' and 'pointed out in theclaims,reference being had to the accompanying drawings, in which Figurelis a side elevation of a portion of an automobile with partsin sectionand showing a deviceembodying the invention applied thereto; Fig.2 is aplan view' of the same with the vehicle body removed; Fig. 3 is an enlared'seotional detail of the device embodyingt e nvention; .Fig. '4' is anor larged sectional view of a valve mechanism; Fig; 5 is "a rearelevation of an automobile r showing a modified form of the inventionapplied thereto; F ig. 6 is a plan view ofthe same with the vehicle bodyremoved; Fig. 7 is a sectional detail showing a furth'eh modification;and Fig. 8 is an enlarged sectional view of a modified construction of'discharge valve. a

For convenience of illustration, the invention is 'shown as applied toan automobile'of' the pleasure type'but it will be ufnd'efstoo'd that itmay be applied as well to any motor vehicle. As shown in the drawings, asuitable frame A is supported upon an axle B which is provided withtraction wheels C having brake drums E. Within each druin are the usualbrake shoes E which are'actu ated in the'usua'l manner through the m'e-(hum of rock'shafts G turned by'means of rods H extending ',forw'ard ly'to arms L se-f cured to a sleeve J in the usual manner upon a crossshaft 'K mounted'in' gbearing's on the frame. The sleeve J is turned'to" actuate thbrakes byineahs' of a rod'eiitending forshaft is actuatedby an emer ency hand lever Ea'ch loralge flrum is al opmvided wlth anexternal bra "elban d O, which ,is operatedin the usual manner throughthe medlum of a f orvifardlyexte ding rod P, whi'chis connected tofan arni on'the s ha K; Motion is transmitted from af o'ot'peiial Q-by meansofa rod R'httached at itsireiar endto an arm S on'the shaft K. All oftheioregoing parts are constructed and arranged to operate in an old'a dwelliknown manner and secured upon t e frame'i's a'vehicle bodyT of anydesir d co n stru'ction' aving"a running board and suitable mud guardsV. Theseihud guaids are preferably 'pi'ovide'd with a 'dpgble .wallforming achambe'r 10 each guard adapted to hold a quahtity of fine sandwhichiiiaybe placed 1n eacphhamber a fill 'openjpggll; Theower'forwardlefid of eachfmud giia'rd ior' 'ned by a suitable valvecasilg lgfwhich' "lsi'fforms a c onnection between the'niud andmimnihg boardU. The casing 121s form 't'w'ovalve seats, one f 'F- p ues l fip va v 1and t (Tithror lower ohe'f 'r a hollo'wrot ary valve e" which isopiiated by' a'n arm 15 secured upon th'e ou't'er'end and to which aconnecting rod 16'Iis pivotally attached at one end,

attached to amocker bar 17 oi' nted up on the crossshaft Kite tu'r'n'free y thereomhetween the arms I and .S. Attached ,to or otherwisearranged to turn each ofthe arms'Lis a short laterally be t 18pmjectingover 'the'fi'ee'end of t e rocker bar 1 ,"and 's e'cured' to' turn witheach of the arms S is a long latei 'ally' extending arm 7 l9i'which' isbent to project over the fijee end pf the bar '17." Coiled s rings 2'0are rovided to'turn the rocker?) rs normally hold the sarne'tur',ed'iyvith their free gangs in eng ement wit the bent ends pf .t" e

i arms"18 'aiid19." Byifason oftheconneetioii between the rocker Roarsand valves 1 4, Qsaid'va'lve's are also turned by the springs m y' ldinclin d pa t nachy'alv'e I3 is turhed gne direction by meansof an ar2'1'on outer end .and'a 'cahle' 22 attachedthei eto and runn ngoi-jwardl'y to the'g'rivers seat where ltis engaged over a tick 23 tohold the valve urned 'to open position against the action of a"oloiled'spring 24. 'A discharge opening 511 v v am a b e mioi e'eesie Ward to anarm on a cross shaft M, which he opposite iid'bf 'Stid,rodibeing pi p 12and a like opening is provided in the valve 14 to register therewith.

When the shut-off valve 13 is opened by means of a cable 22, sand willpass through the valve into the hollow discharge valve below, and uponoperation of the service brakes by means of the foot pedal Q, the longarms 19 on the rock shaft K will be turned into engagement with therocker bars 17 and the valves 14 will thus be turned a short distance asshown in Fig. 4, or far enough to open the discharge 25 part way andpermit a small amount of sand to escape. When it is necessary to stopthe car quickly and the emergency brakes are operated by means of thehand levenN, the short arms 18 will be turned thereby into engagementwith the rocker bars 17 and actuate the valves 14. As the arms 18 areshorter than the arms 19, the rocker bars will be turned farther andthus open the valves to their full extent. For ordinary running a smallamount of sand is permitted to escape when the service brakes areoperated but when an emergency occurs requiring the use of the emergencybrakes a larger quantity ofsand is automatically released.

In Figs. 5 and 6 a modified construction is shown, the supply of sandbeing carried in a receptacle 26 located at any convenient point in thebody, and provided with a bottom discharge leading to a valve casingsimilar to the casings 12 and from which casing the sand is conducted bymeans of discharge pipes 27 to the forward side of each driving wheeladjacent to the road bed. The valve casing contains valves 13 and 14 forcontrolling the flow from the receptacle 26 which are operated the sameas previously described.

In Fig. 6, the sand box 26 is shown as having a double wall and intothis space 28 between the walls is conducted hot exhaust gases from theexhaust pipe 29 of the motor, through a connecting pipe 30 0 eninglaterally from the exhaust pipe w ich is provided at its outer end-witha cut out valve 31 which permits gases to escape directly from the pipeto the open air. The hot exhaust gases are thus utilized to heat thesand box and keep the sand warm and dry therein so that it willdischarge freely.

When the mud guards are utilized as receptacles for the same, thedischarge of the sand may be assisted by forming each valve casing witha hollow wall or jacket as shown in Fig. 8, and conducting hot gasesfrom the exhaust pipe 29 into the chamber 38 thus formed in the valvecasing, through a pipe 39, opening into the lower end of each casingthrough an inlet passage 32 which opens directly into the side of adischarge passage 33 for the sand leading from the lower side of thevalve 14:. An opening 34 from the passage 32 into the jacket 38 permitssome of the hot gases to escape into the jacket around the valves andheat the same so that they will turnfreely and the sand containedtherein will bethoroug'hly dried. A

'When traveling over wet and slippery pavements it may be founddesirable to (118* charge a small amount of sand while the car is movingforward and the brakes are inoperative, to prevent the car from skiddingor sliding sidewise. To permit such continuous esca c with but thenecessity of operating the rakes, a bypass is formed around each valvecasing by providing a small tube 35 as shown in Fig. 8, adjacent to therear side of the casin and openin at 1ts uplpe end into the supp ychamber a ove the s utofi valve. This tube is provided with a valve 36which may be operated by a rod 37 or in any other suitable manner tocontrol the flow throu h the tube. 1

Obvious y changes may be made in the construction and arrangement ofparts without departin from the spirit of my invention, and I 0 notlimit myself to the particular form or arran ement shown.

Havin thus fully escribed my invention what I c aim is 1. Thecombination with a motor vehicle having service brake operatingmechanism and emergency brake operating mechanism, of a receptacle onthe vehicle having an out let positioned to discharge material in thepath of the vehicle wheel, and means for controlling said outletoperated by each of said mechanisms independently of the other. 2. Thecombination with a motor vehicle having a lurality of controlling mechanisms, of a receptacle on the vehicle hav= ing an outlet adjacent to theforward side of the vehicle wheel for the discharge of material into thepath of said wheel, and means controlling said outlet operated bydischarge a limited amount of material and operated independently by theactuation of the other of said mechanisms to discharge a greater volume.

3. The combination with a motor vehicle having traction wheels and brakemechanism for said wheels, of a receptacle having an outlet in the-pathof the wheels, a valve actuated by the operation of the brake mechanismto control the discharge of material from said receptacle, and ashut-oft for said outlet.

4. The combination, with a motor vehicle having a motor exhaust pipe, ofa receptacle on the vehicle for material to be discharged in the path ofthe vehicle wheels, means for conducting hot gases from the exhaust pipeto said receptacle to heat the same, and means for controlling thedischarge of material from said receptacle.

- 5. The combination with a motor vehicle, having controlling means, ofa receptacle on the actuation of one of said mechanisms to the vehiclehaving an outlet passage, a controlling valve in said passage, means forautomatically operating said valve by the actuation of the controllingmeans, an auxiliary passage, and a manually operated valve controllingsaid auxiliary passage.

6. The combination with a motor vehicle having controlling means, of areceptacle on the vehicle having a discharge passage, a manuallyoperable shut-off valve in said passage, an automatically operated valvein said passage below the shutofi' valve, means actuated by thecontrolling means of thevehicle for turning said automatic valve, anauxiliary passage opening into the main passage above the shut-offvalve, and a manually operated valve in said auxiliary passage.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN F. WILLIAMS.
